WINDOW SCREEN CONSTRUCTION Filed NOV. 8, 1928 VPatented May 26, 1931 UNITED STATES PATENT OFFICE WINDOW SCREEN CONSTRUCTION Application filed November 8, 1928. Serial No. 317,985.

This invention relates to window screen construction.

Objects of this invention are to provide a novel form of window and window screen which is so made that a combined casing and screen panel construction is provided, so that it is not necessary to put up and take down the screens with constant wear thereto, which has heretofore been the case, but in 10, which the screen is attached to a sash so that it is always available and may be easily released therefrom if desired, thus permitting the windows to be washed from the inside of the house at any time.

Further objects are to provide a construction in which the window may be opened to any desired extent, as required for ventilation, and in which the screen correspondingly adjusts itself to the selected opening of the window.

Further objects of this invention are to provide a construction in which the screen projects from the window sash and forms in effect a continuation thereof, and in which a solid portion of the screen frame seats snugly within a slot, so that an airetight and water-tight joint is formed. j

An embodiment of the invention is shown in the accompanyingdrawings, in which:

Figure l is a front View of the window, with parts broken away.

Figure 2 is a transverse sectional view.

Figure 3 is a detailed sectional view, showing the lower sash and the associated parts. Referring to the drawings, it will be seen that the usual type of window casing l, which has been illustrated, is provided with a window sill 2 and with a pair of sashes 3 and 4. Either or both of the sashes may be provided with the screen attachment. For simplicity, the lower sash only has been shown in the drawings as equipped with the screen, although obviously both sashes may be so equipped without departing from the spiritr of this invention. This lower sash is provided with a rectangular groove extending across its bottom, which receives the upper solid portion of the window screen frame 5.

This window screen projects downwardly 55 and passes through a slot 6 formed in the and downwardly,

window sill so that it may slide upwardlyas the sash 3 is adjusted. The frame is held within the groove in the bottoni sash by means of a spring-pressed plunger '7, secured to the sash as shown in Figure 3. Thus, it is a very simple matter to detach the window screen from the sash whenever it is desired.

Further than this, when the window is closed, the solid upper portion of the window screen frame snugly fits within the slot, as shown in Figure 8, and thus forms an airtight and water-tight joint.

It will be seen that a simple, serviceable and relatively cheaply produced` construction has been provided, which has the advantages enumerated above.

Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting, as the invention may be variously embodied and as the scope of such invention is to be determined as claimed. f

I claim:

In combination with a sash having a longitudinal groove and a transverse bore communicating with the groove, a casing attached to one side of the sash and a spring-pressed bolt arranged within the casing with one end projecting through the bore and traversing the groove.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Viisconsin.
